摘要
针对航空航天、国防军工领域内飞行器飞行实验中残骸和存储器的快速、准确、高效的定位回收问题,创新性地利用RNSS和RDSS相结合的卫星通信方式并利用包括国产单片机在内的国产器件,设计了一种高可靠高精度的全国产化实现落点定位的定位系统。经过多种复杂恶劣环境下的实验与应用,系统的定位精度最高可以优于5 m,北斗短报文的通信频度在2次/分,丢包率小于5%,大容量锂电池可以保证系统连续最长工作时间达4 h;满足对残骸和存储器的定位回收需求,具有体积小、高精度、高可靠性、实时性强等特点。目前已经在某项目中得到应用。
In response to the problem of fast,accurate,and efficient positioning and recovery of debris and memory in aircraft flight experiments in the fields of aviation,aerospace,national defense,and military industry,an innovative satellite communica-tion method combining RNSS and RDSS and domestic devices including domestic microcontrollers are used to design a highly reli-able and high-precision nationwide localization system for landing point positioning.After various experiments and applications in complex and harsh environments,the positioning accuracy of the system can be as high as 5 m.The communication frequency of bei-dou short messages is 2 times/min,and the packet loss rate is less than 5%.The large capacity lithium battery can ensure that the system can work continuously for up to 4 hours.It meets the positioning and recycling needs of wreckage and storage,with character-istics such as small size,high accuracy,high reliability,and strong real-time performance.Currently,it has been applied in a cer-tain project.
